The timer created under the hood by AbortSignal.timeout() is unref-d. This means if there is no other activity keeping the event loop running, the node process will exit. For this standalone example, the npm run script is requiring keep-process-alive.js to keep the node process running while we wait for the abort signal timer to run.

Example B

Create an abort signal which triggers after 200 milliseconds and cancels an HTTP request.

Requires Node.js >= v17.5.0 as it uses the experimental Fetch API.
